【摘要】 目的临床观察拉米夫定干预下慢性乙型肝炎孕妇的病毒动态及安全性。方法对拉米夫定治疗中发现早孕而继续服药的18例慢性乙型肝炎孕妇及发现早孕而停止服药的22例乙型肝炎孕妇,分别观察其病毒动态、妊娠并发症、婴幼儿HBV感染率及发育异常发生率。结果18例继续服用拉米夫定治疗的慢性乙型肝炎孕妇中16例HBV-DNA阴性,18例孕妇所产婴儿HBV感染率为零,妊娠并发症为零,尚未发现婴幼儿发育异常情况。而停止服药的22例慢性乙型肝炎孕妇中,19例HBV-DNA阳性。其婴儿HBV感染率41.9%,有17例发生妊娠并发症。结论拉米夫定可有效降低孕妇HBV-DNA水平,有助于阻断母婴传播,也有助于降低乙型肝炎妊娠并发症。更多还原
